Abstract
Barathrites iris Zugmayer, 1911 is an abyssal fish species inhabiting depths exceeding 3,000 m. We successfully sequenced and characterized the complete mitochondrial genome of B. iris, which represents a closed circular molecule of 16,646 bp with a GC content of 48.98%. Phylogenetic analysis of Ophidiiformes based on whole mitochondrial genome sequences demonstrated that B. iris forms a sister group with Penopus microphthalmus while supporting the polyphyly of Bythitidae as well as the paraphyletic status of Ophidioidei. As the first report of a complete mitochondrial genome for B. iris, this study provides valuable genomic resources for investigating deep-sea adaptation mechanisms in Ophidiiformes and contributes to our understanding of evolutionary patterns in abyssal teleost fishes.
期刊介绍：
This open access journal publishes high-quality and concise research articles reporting the sequence of full mitochondrial genomes, and short communications focusing on the physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism and interactions.
